Quizplus · Accepted Answer

The frequency of oscillation of a spring-mass system is given by:

f = (1/2π)√(k/m)

where k is the spring constant and m is the mass.

Substituting the given values, we get:

f = (1/2π)√(290/2)

f ≈ 1.9 Hz

Therefore, the best choice is D) 1.9, which is the closest option to the calculated frequency.

A Mass M = 2
